showing image not working

Hi all,

i'm trying to output an image in a controller action. However i can't get it to work. If i run the same code in a regular php file it runs fine, but when i run it in a controller i can't get it to work.

    /**
     * @param $systemName
     */
    public function overviewAction($systemName)
    {

        $tournament = Tournament::findFirstBySystemName($systemName);

        if ($tournament) {

            if ($image = (string)$tournament->challonge->getOverviewImage()) {
                $this->response->resetHeaders();
                $this->response->setHeader('Content-Type', 'image/png');

                $tmpFile = $this->config->application->cacheDir . $systemName . '.png';
                file_put_contents($tmpFile, file_get_contents($image));


                $original = new \Phalcon\Image\Adapter\GD($tmpFile);
                $original->crop($original->getWidth(), $original->getHeight() - 150);
                $original->save();

                readfile($tmpFile);
            }
        }

        $this->view->setRenderLevel(View::LEVEL_NO_RENDER);
    }

I have tried it with a die at the end, setting headers in the normal fashion, different ways of outputting the file, removing the renderLevel thing etc.

Am i missing something?

Thanks!

Check permissions of files and folders. Example : when you run script in console - script work and create/change files as "user" when you run on server - work wtih files and folders are via user (and group) "http" or "www-data" or other (see your server setup)

Nothing to do with permissions :)

If i disable the bootstrapper and run the same code it outputs the file in the browser.

readfile($tmpFile);

Why you use this?

Check the PHP documentation for readfile()

readfile($tmpFile);

Why you use this?

Is the tmpfile being created?

What output are you actually seeing?

Open the browser dev tools and see what headers are being sent.

Everything works well, like i said using plain php everything works. Only doing it in a controller fails somehow.

All headers:

In one of your if statements, you have "challonge" - should that be "challenge"?

Try simplifying it - just for testing. Don't use $this->response() to set the headers, just use PHP's header() function. Also, just call readfile() on the image, don't resize and try to output the thumbnail.

Btw this is still an issue. Outputting images in the controller simply does not work.

It is a late reply, but I wonder why do you use readfile whereas you could just render it, something like this

$this->response->setHeader("Content-Type", $original->getMime());
$this->response->setContent($original->render());
$this->response->send();
return;

Btw this is still an issue. Outputting images in the controller simply does not work.

It was not about the php code. Render does exactly the same thing. It was not outputting the image regardless of what i used.

Hi,

I'm using

        $response = new Phalcon\Http\Response();
        $response->setContentType('image/jpeg');
        $response->setContent(file_get_contents($file));
        return $response;
